This is a list of free and pay wall blocked digital online newspaper archives. Most are scanned from microfilm into pdf, gif or similar graphic formats and many of the graphic archives have been indexed into searchable text databases utilizing optical character recognition (OCR) technology. Some newspapers do not allow access to the OCR-converted text until it is proofread. Older newspapers are still in image format, and newer newspapers are available as full text that can be cut and pasted. Most text is in ASCII, some are using Unicode for diacritical marks not available in ASCII. Google now indexes many newspaper archives.
